Everyone else talked about outdoor cats, it's time for me to talk about offleash dogs
Reasons not to have your dog offleash at a public park:
1) roads (this one is self-explanatory)
2) it makes the park inaccessible to like, entire swathes of the population. If you have experience with police dogs or guard dogs in your neighborhood, or you're a new immigrant from somewhere with a large population of feral dogs, it sucks ass going to the park and having someone's massive lab bound up to you!
3) If, for example, you are in a protected wetland area plastered with friendly signs asking you to please leash your dog to avoid causing an ecological impact, having your dog offleash might cause an ecological impact! "Oh no, my dog is well-behaved, they would never bother the wildlife" wrong! your dog is in the pond trying to eat the endangered Blandings' turtles!
4) Non-zero chance of a jokerified park guide (me) just clipping your dog to a leash and stealing them
Unleashed dogs were the bane of my existence when my little girl was like 5 or 6. My daughter just had this weird little thing where she is scared of animals twice her size sprinting up to her, knocking her over, and then invading her personal space despite her being clearly distressed.
"Oh don't worry they don't bite!" First off, I don't believe you actually know that for sure. Second, that is hardly the only problem here. My daughter was so scared of dogs that she would cry and had to be picked up and protected to feel safe whenever she saw one for years because of this bullshit.
